Robust Data or Functions

A few years ago I became interested in education statistics. These statistics are readily available at the National Center for Education Statistics. NCES is filled with data regarding every aspect of the American educational system. At this website, you can find statistics about spending, dropouts, numbers of students, number of teachers, students with disabilities and more at the national level down to the county and district level. Using the data tools at NCES, I was able to create an Excel file (and corresponding PDF) containing the number of students and teachers in each state for the years 2000 to 2006.
